Arigid tank is filled initially with 5.0 kg of air at a pressure of 0.4mpa and a temperature of 500 k. the air is allowed to discharge through a turbine into the atmosphere, developing work until the pressure in the tank has fallen to the atmospheric level of 0.1 mpa. employing the ideal gas model for the air, determine the maximum theoretical amount of work that could be developed, in kj. ignore heat transfer with the atmosphere and changes in kinetic and potential energy.
